I got 4 answers correct but none registered . On one occasion it was because I did not put dots after the initial letters of the author and on the other three occasions I can only assume that it was due to the spacing between the initials and the surname of the author , so this quiz has been badly designed , as it's too inflexible and unable to recognise correct answers. The compiler alos seems to be heavily obsessed with books that have been made into ( mostly recent ) films.
